LOS ANGELES — It felt like a wrap party for a big-budget Hollywood flick at Disney’s El Capitan Theatre, complete with fancy food and big names like Pixar chief John Lasseter in attendance. But Disney’s Infinity announcement on Tuesday was a massive project in which Pixar, the Disney-owned digital animation studio that once belonged to Steve Jobs, played only one of the major roles.

As it was revealed, Infinity is an amazing, massive, cross-platform, multiplayer game system based on figurines from the Disney catalog of movies — right now most of them specifically from Pixar titles.

“It will be global, and it will live across all platforms: console, mobile and online,” Lasseter said on Tuesday.

All platforms? Unfortunately not. Perhaps Disney has forgotten that Steve helped build Pixar into the powerhouse it is today; because while a Windows version will be present along with versions for all the major console systems at Ininity’s June launch, there won’t be a Mac version — at least, not at first.
